EN590 10PPM/50PPM

Description

Although EN**0 covers numerous fuel characteristics, water content is the most relevant contaminant for fuel maintenance. To comply with EN**0, fuel can contain no more than **0mg of water per kg of fuel.
This is an extremely demanding standard. **0mg of water per kg of fuel represents just 0.*2% water contamination. Because modern biodiesel blends absorb water naturally (i.e. they are hygroscopic) it is practically impossible to adhere to the standard without regular testing and the use of a water extraction process such as a polishing system or regular tank cleaning.
